Choose a zero-sugar cola if you want cola flavour and do not need to avoid caffeine; choose a separately labelled caffeine-free version if caffeine matters to you in the afternoon. For a non-cola drink, look at the exact pack rather than assuming that every fruit-flavoured option is sugar free or no added sugar. Check the ingredients as well as the sugar figure, particularly if aspartame or its phenylalanine warning is relevant to you.
If the drink needs to be zero sugar, sugar free or explicitly no added sugar, check that wording on the particular product and read its nutrition panel. A flavour or a fizzy-drinks category is not enough to identify the right pack.
If you want cola flavour without caffeine later in the day, look for a separately named caffeine-free variant. Standard and caffeine-free zero-sugar colas are not interchangeable on this point.
Read the ingredients of the exact drink if you avoid a particular sweetener. Aspartame and the associated phenylalanine notice are especially important checks for people with phenylketonuria (PKU), as the Food Standards Agency identifies aspartame as a possible risk for them.
Start with the type of drink you want, then check the claim, ingredients and pack size on the individual product.
Choose it when: You want cola flavour and caffeine is acceptable. Coca-Cola Great Britain and Pepsi UK list caffeine in Coca-Cola Zero Sugar and Pepsi MAX respectively.
Bear in mind: The checked drinks also list sweeteners, including aspartame; their sugar claims do not remove the need to read the ingredients.
Choose it when: You want cola flavour but prefer to avoid caffeine. Coca-Cola Great Britain and Pepsi UK identify separate caffeine-free zero-sugar variants.
Bear in mind: Caffeine-free does not mean sweetener-free, so check the selected variant’s ingredients and warning.
Choose it when: You would rather have a fruit, lemon-lime or other non-cola flavour with your snack.
Bear in mind: Flavour and range names do not establish the sugar, caffeine or sweetener details of every variant.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar claim | Read the exact product wording and sugars per 100ml on the nutrition panel. If you specifically require a “no added sugar” claim, do not substitute “zero sugar” without checking the pack. | I want the drink I buy to match the sugar claim I am looking for, not merely to sit in a sugar-free range. |
| Caffeine | Look for an explicit caffeine-free variant and check its ingredients. Coca-Cola Great Britain and Pepsi UK distinguish these from their standard zero-sugar colas, which list caffeine. | For an afternoon cola, I would rather choose a version explicitly labelled caffeine free. |
| Sweeteners | Check the complete ingredient list and any phenylalanine notice. The Food Standards Agency identifies aspartame as a possible risk for people with PKU. | If PKU or a particular sweetener matters to me, the sugar figure alone cannot settle my choice. |
| Pack size | Compare the number of cans, volume per can and total volume. Check the best-before date and how you would store a multipack. | Individual cans may suit my snack routine, but I need a multipack size I can use and store. |
A retailer’s category or a familiar flavour name does not establish the sugar content of the particular drink you pick up.
Check its current product name, nutrition panel and ingredients. If you need an explicit “no added sugar” claim, find that wording on the selected pack.
Coca-Cola Great Britain and Pepsi UK list caffeine in standard Coca-Cola Zero Sugar and Pepsi MAX; their caffeine-free versions are separate products.
Check for “Caffeine Free” in the precise variant name, then recheck the ingredients if you switch packs or flavours.
Some checked zero-sugar colas contain aspartame and carry a phenylalanine notice. The Food Standards Agency identifies aspartame as a possible risk for people with PKU.
Read the full ingredient list and warning on the selected pack if PKU or a sweetener preference affects your choice.
A zero-sugar claim alone does not establish whether a drink meets the requirements for food and drink provided to pupils in England.
For school catering, check the current Department for Education school-food standards, the rules applicable to the school’s nation and the full product specification.
Brand families contain different variants, so use these references to identify the product label you need to check rather than assuming every drink from a brand has the same recipe.
Coca-Cola Great Britain lists both Coca-Cola Zero Sugar and a separately named Caffeine Free variant for cola shoppers.
Pepsi UK distinguishes Pepsi MAX from Pepsi MAX Caffeine-Free.
Sprite Zero Sugar is a lemon-lime option for shoppers who do not want cola flavour.
Fanta Zero Orange and Fanta Zero Fruit Twist are fruit-flavoured options to consider instead of cola.
Dr Pepper Zero offers another flavour choice within a sugar-free fizzy-drinks range.
Tesco’s own-label range includes a product named No Added Sugar Ginger Beer.
These Joybuy options cover caffeine-free and standard cola, plus non-cola sugar-free drinks in cans. Match the exact sugar claim, ingredients and pack size to your afternoon snack.

A cola option for an afternoon snack when caffeine-free wording matters. The pack contains 24 individual 330ml cans; check the current sugar claim and ingredients, including the phenylalanine notice, before choosing it.
No image available
Choose this separately named variant if you want Pepsi MAX cola flavour without caffeine. It comes as 24 individual 330ml cans; check the pack’s sweeteners and phenylalanine notice if either affects your choice.

This standard Zero Sugar cola comes in 24 individual 330ml cans. Coca-Cola Great Britain lists caffeine and aspartame for the standard variant, so choose the separately named Caffeine Free product if you need to avoid caffeine.
No image available
A non-cola option in an eight-pack of 330ml cans. Check the current pack if your requirement is specifically “no added sugar”, and read its ingredients and phenylalanine notice before choosing.
No image available
An apple-flavoured alternative to cola, supplied as 24 individual 330ml cans. If caffeine or a particular sweetener matters to you, check the current ingredients; also confirm the pack wording if you specifically need a “no added sugar” claim.
Do not treat the phrases as interchangeable when your requirement depends on the exact claim. Check the selected drink’s current wording, nutrition panel and ingredients; Tesco Groceries, for example, lists products named “No Added Sugar” separately from products named “Zero”.
Look for a variant explicitly labelled caffeine free, such as Pepsi MAX Caffeine-Free or Coca-Cola Zero Sugar Caffeine Free. Pepsi UK and Coca-Cola Great Britain distinguish these from standard Pepsi MAX and Coca-Cola Zero Sugar, which list caffeine.
Some zero-sugar drinks contain aspartame and carry a notice that they contain a source of phenylalanine. The Food Standards Agency identifies aspartame as a possible risk for people with PKU, making the ingredient list and warning important checks on the exact product.
No: the sugar claim alone does not establish suitability for school catering. For food and drink provided to pupils in England, check the Department for Education’s current school-food standards and the full product specification; check the applicable rules separately in other UK nations.
Check the number of cans, the volume of each one and the total amount you will need. A multipack makes sense for your routine only if you have space for it and can use it within its best-before date.
